ELECTRIC HEATER.

`Application led December 19, 1927. Serial No. 241,104.

The invention relates to improvements. in electric heaters by means ofelectric heatmg wire extending around a porcelain tube inclosed by aconcave reflector which is attached' within the walls of theheater; andby a humidifier located above reflector under top menting the radiantheat from heating wire;

third, to cause hot air `from the vacuum of the reflector to becomehumidified by vapor from water in a receptacle located in hot airpassage under top of heater.

One form of the invention is illustrated in the accompanying drawing, inwhich Figure l is algeneral View 0f heater, indicating air outletthrough top. Fig. 2 is an interior view of heater, showing location ofheating element, concave reflector with perforated cold air inlet andlocation of the humidifier under top of heater. Fig. 2 also indicatesthe manner said vparts are attached. Fig. 3 shows an end View ofhumidifier and its position under top of heater. Fig. 4 is adetail Viewof heating element, showing the position of the porcelain tube in thesocket of the terminal block, the arrangement of the heating Wire' andthe manner the heat-ing element is attached to reflector. 1

Figure 1 illustrates hot air outlet 2 in heater top l; the position ofwaterA tube 3 by which water is put in the humidifier; the humidifierwater gauge 4; and the manner in which the heater is held together withflat head bolts 5.

The lower edges of heater are bordered withnarrow piece 7, said bordersoldered to edges. In Fig. 2, bolts 5 extend through top Vof heater,through rectangular reflector support 14, through edge l5 of heater tonut soldered under said edge 15. AHeating' ele ment 10 is screwed toreflector 6. The reflector is supported by being bolted to rectangu= larsupport 14. l Reflector support 14 has air passage at top of reflectorsame size as opening 18. Humidifier 16 is held in place under top ofheater on one end by Water tube 3 which is soldered to top of heater andsaid humidifier, also by Water gauge tube 4 which is attached insame-manner. At the other end 'the humidifier is soldered to strip 17which is attached in same manner to side of' top. The humidifier has, asindicated, perforated outlet for vapor. In filling humidifier, water ispoured through tube 3 until it appears inv gauge tube 4, whichindicates-the level of the Water in humidifier. In Figure 3, thehumidifier 'is shown with one side beveled in order that it may fitclosely against beveled side of top. The short beveled portion ofhumidifier near top contains the perforated outlet for vapor. In Figure4, heating wire extends from terminal through porcelain tube 10, passingthrough small holes at ltop of tube and in spiral manner around tube tobase of same, said heating wire lf3 extends through hole in base andterminal block to terminal as indicated. Porcelain tube 10 with baseandsmall cylindrical end fits into socket. of terminal block in mannerillustrated in Fig. 4. Two small `screws eX- tending through terminalblock cover 9 into terminal block, hold said cover in place. A portionof inside wall of cover-9 near its edge is threaded in orderthatsaidcover with terminal block and complete heatingelement maybe attached toreflector 6, screwed on lower portion of reflector' at 8,
